[CMake] Eclipse: sources out of CMakeLists directory

[Andrea Galeazzi]

In many of my subprojects I've got some sources outside of CMakeLists 
directory. This is an example:
C:\Product1\project1\CMakeLists.txt
C:\SharedFiles\dir1\foo.cpp
C:\SharedFiles\dir1\foo.h

Unfortunately Eclipse doesn't show them in the Project Explorer view. 
Should it be possible to request a feature in order to be able to show 
these files too?

Cheers
